There are itineraries as long as 14 nights with stops all up the Coast, and as short as 1 night going between Seattle and Vancouver. Most of these itineraries are in April, May and September when the ships are repositioning for the Summer Season, but one line, Princess has a roundtrip Los Angeles, U.S. Pacific Coastal trip in October as well.
Any of these are great values for a great quick "getaway". As an example, even the one night trip, would be great financially speaking. Think about it, you are staying at a nice "hotel", ocean views, amazing dinner, even a Broadway style show, all starting at about $49 per person (plus taxes). Any piece of this I mentioned above is worth more than $49 per person. A couple years ago I had a passenger book a 3 day voyage for his 10 year anniversary, and he invited and paid for 25 of his family and friends, and the total bill for the party was under $4000, and the cruise line even had a private cocktail party for him. You want to try that with any other "hotel"?
I have found these trip just a great way to get away from it all for a few days, and enjoy myself, and above all, relax.
Has anyone one else tried these out? If you have, let me know about your experiences, and if you want to go on one let me know.
